[ovirt-users] Moving Hosted Engine NFS storage domain

[Beard Lionel (BOSTON-STORAGE)]

Hi,

I have followed these steps :


-          Stop supervdsmd + vdsmd + ovirt-ha-agent + ovirt-ha-broker

-          Modify config file

-          Copy files (cp better handles sparse files than rsync)

-          Umount old hosted-engine path

-          Restart services

-          Hosted VM doesn't start => hosted-engine -clean-metadata. I get an error at the end, but now I am able to start Hosted VM :

o   ERROR:ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine:Metadata for current host missing.

I can connect to oVirt interface, everything seems to be working fine, but the Hosted storage domain has an incorrect path, it is still pointing to old one... I think this information is not correctly reported by web interface, because this path doesn't exist anymore, and hosted VM is working !
Does anyone knows how to fix that ?

Regards,
Lionel BEARD

Hi,

I'm trying to move Hosted storage from one NFS server to another.
As this is not a production environment, so I gave a try with no success, with a plan similar to yours.

But I don't like to stay on a failure, so I will give a second chance by following your plan :)

Hello,

         we would like to move our NFS storage used for the HostedEngine.



Plan would be

  *   enable global maintenance
  *   shut-down HostedEngine VM
  *   edit  /etc/ovirt-hosted-engine/hosted-engine.conf on hosts

     *   storage=newnfs:/newnfsvolume

  *   copy storage domain from old to new nfs server
  *   start HostedEngine VM
  *   run engine-setup on HostedEngine VM
  *   disable global maintenance

Has anyone had any experience doing this?

Have I missed any steps out

we are currently running oVirt 3.6.2



Thanks,

              Paul S.
